Home button does not work when the phone is locked
Today I repair my phone (iphone 6) screen replacement on a firm, after the change is so weird Home button.
button works perfectly when the phone is unlocked. but when the phone has been locked in maybe 1 minute, then do not work at all, then I have to press the power button on the side, afterwards operate the Home button again until the phone locks the next time.
Please help me, are curious and want to know if it's something simple wrong or I have to run back with it and use the guarantee
